Seems like a really good price since it includes cats... too bad they're in the wrong location.

Let me get this straight... You are swapping out parts designed by some of the top engineers in the world because some guys sponsored by a company told you it's "better??" But when you ask the same guy about tracking, "oh no, I have a kid now" or "I just detailed my car." or "i just got new tires."

What do you mean by wrong location? They're in the same place as the primary cats aren't they? Or would you rather secondary cats?

I guess I should have put IMO. Some would want the cats in the primary location and hope to not get a check engine light, but most would just get a tune for the check engine light and to optimize power, and take the cats in the secondary location so it doesn't smell too bad- while still get most of the power gains that a straight pipe would give you.

A resonator option would be nice too for rasp as mentioned above.

I just recently (few days ago) had this X-pipe installed along with a Remus race rear section. Car is very loud now, especially on cold starts. Very deep sounding exhaust at low revs, but starts screaming after about 3500-4000rpm, very F1 like. As well, no CEL.

Sounds loud but good! Are you using the stock ECU or an aftermarket tune? Curious about the no CEL. Keep us updated if it throws a CEL eventually as other HFC setup's do.

Its extremely loud, the shop that installed it said its one of the loudest exhausts they've heard haha... Just a stock ECU, looking into getting a tune next year probably. I hope that day doesn't come but if it does just an excuse to get it tuned sooner!

Thanks for the info! I've been tempted to get it (love their intakes on both of my cars!) but reluctant since I haven't heard of any HFC setup that doesn't trip the CEL (with the stock ECU). After you (and/or a few more people) rack up 4k - 5k miles & still have no issues then I'd be very interested.
